I there any fast algorithm for computing e^e to high precision?

Thanks

With Mathematica 5 on a mac G5

N[E^E,1000]

takes 56 microseconds. N[E^E,10000] takes .132 seconds. Why
do you want to do it yourself?

Mathematica is not accurate. The first thousand digits of N[E^E,1000]
is different than the first thounsand digits of N[E^E,10000]

The results are consistent, given that N[E^E,1000] gives a result that is
rounded to 1000 significant digits. If you want the result truncated to
1000 significant digits instead of rounded, you can take the first 1000
digits of N[E^E,1010].
